Title: Combustion air control device
Inventor: YOSHIDA YUTAKA
IPC: F16K31/04
Filed: 1990-05-16
Abstract: PURPOSE:To stabilize a rotation reference position of a damper and control the amount of air with accuracy by installing a stopper, which provides a reference position to the damper when it rotates, to at least two positions on their opposite side, centering on the rotary axis of the damper. CONSTITUTION:When starting up operation, a stepping motor is rotated so that a damper 16 may come into contact with a stopper 19 where this contact position is set to a rotation reference position of the damper 16. When the damper 16 is located at this position, it is set that the amount of combustion air passing through the damper should be a minimum one or the amount of air required for weak combustion. A stopper 19 is installed at two positions. They are installed so that they may virtually face each other, centering on a rotation axis 16c of the damper 16. The damper 16 is forced to receive torque with the two stoppers 19, centering on the rotation axis 16c, which prevents the rotation axis 16c from being inclined. As a result, the damper 16 can be set at the reference position with accuracy, which makes it possible to keep accurate the rotation position of the damper 16 at each combustion amount in the following steps.

Filed: 1985-06-12
Abstract: PURPOSE:To permit polishing machining of a workpiece in a high grade of roundness with a small cutting resistance by making small vertical reciprocating motions of a rotating hone and large vertical reciprocating motions of sard hone corresponding to the machining length of the workpiece in the case of polishing machining. CONSTITUTION:When a hone 2 equipped to a main spindle 3 is rotated horizontally by a rotation drive source 15, an eccentric tire 6 is also give rolling movement on the upper surface 7a of an annular seat 7. In this case, the axial center of the eccentric tire 6 and the axial center of a radial bearing 5 are eccentric with each other to the extent of eccentricity 6a, therefore, when the main spindle 3 is rotated once, the main spindle 3, namely the hone 2 makes small vertical reciprocating motions across a distance of two times of eccentricity 6a. Furthermore, when a ball screw 50 is rotated by a rotation drive source 51, a spindle head 300 makes large reciprocating motions vertically within a headstock 301 and results in large reciprocating motions of hone 2. By overlapping horizontal rotations of the hone 2 on the above reciprocating motions, honing machining of a workpiece W can be made with small cutting resistance and in a high grade of roundness.
